Public bug reported:
A command as simple as
whiptail --infobox Hello 0 0
prints nothing in xterm-like terminal emulators while it shoud draw a box with
Hello written inside.
I was able to understand what whiptail is doing with this strace command :
strace -e t=write -s 5000 -o trace whiptail --infobox Hello 0 0
When whiptail processes the --infobox option, it does this :
switch terminal to alternate screen
draw information box
switch back to normal screen
exit
The effect is that it is not possible to see the information message.
Infobox messages are supposed to be displayed for a long time...
whiptail should not switch screen in this case.
